Infrastructure Specialists

Our survey team brings decades of experience—from field surveys to data analysis and plan creation. Drawing from our extensive archives, we "walk in the footsteps" of those who came before us to gain historical context and precision.  

We employ the latest technology, including robotic total stations and GPS systems with both RTK and machine control, ensuring streamlined construction and efficient layouts in the field.

Founded in 1964 as a structural engineering firm, Dumack Engineering brings more than 60 years of expertise in building and infrastructure design. 

We’re intimately familiar with high-wind and seismic code requirements—both nationally and internationally. Our portfolio spans industrial structures (hoppers, bins, silos in power & utility sectors), process facilities up to 300 feet tall, as well as residential and commercial buildings. 

We provide comprehensive civil design services across commercial, industrial, residential, and recreational projects. Our civil team combines personal collaboration with clients and regulatory agencies with the highest professional standards. 

From small parking lots to large-scale land developments, we handle it all—from feasibility and permitting to final construction documents and approvals. 

Our environmental team specializes in sanitary and water infrastructure—from septic system design and infiltration testing to soil evaluations. We also conduct Phase I Environmental Assessments and oversee Act 2 cleanups. Using modern modeling and simulation tools, we optimize designs for efficiency, compliance, and sustainable outcomes. 

With deep roots in our region, Dumack Engineering has a long tradition of serving municipalities, boroughs, and authorities. Our municipal engineering services include plan reviews, land-use and zoning planning, public project design, stormwater and floodplain management, contract document preparation, project administration, and inspection oversight. 

We deliver comprehensive construction inspection and oversight for commercial, residential, and public works projects. Collaborating closely with owners, developers, officials, and contractors, we adapt to evolving site conditions and offer timely, practical recommendations throughout construction. 

Whether planning, designing, renovating, or maintaining water and sewer infrastructure, Dumack Engineering provides expert guidance every step of the way. Our engineers offer environmentally sensitive, cost-effective solutions tailored to growing communities across the Tri-State area. 

Our landscape architects craft forward-thinking design solutions for site development, sustainable infrastructure, and green spaces. From recreational parks and urban playgrounds to streetscapes and community pools, every project integrates sustainability and environmental stewardship alongside aesthetic function.
